Abstract
A touch display panel and a display device are provided. The touch display panel includes: a plurality of touch electrodes, a plurality of touch signal lines, a plurality of demultiplexing circuits, a plurality of touch channel signal lines, a plurality of pads, and a driving chip. The demultiplexing circuits can selectively electrically connect one of multiple of the touch signal lines to a corresponding one of the touch channel signal lines. A number of the pads can be decreased, and layout design space required by the touch channel signal lines and the pads can be reduced, so as to increase freedom of selection of the driving chip.
